POLE-SOCKET.

SPECIFICATION forming part Of Letters Patent No. 725,685,

dated April 21, 1903.

Application filed February 13, 1903. Serial No. 143,239. (No model.)

To all whom, it may concern:

Be it known that I, BERNARD D. DRUEN, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new and usefulImprovement in Pole-Sockets; and I do herebydeclare the following, whentaken in connection with the accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and exact description ofthe same,and which said drawings constitute part of this specification,and represent, in-- Figure l, a top or plan View of apole-socket with apole therein constructed in accordance with my invention; Fig. 2, a sideview, partially in section, of the same; Fig. 3, a transverse sectionalview through the socket; Fig. 4, a perspective view of the pole-sleevedetached; Fig. 5, a perspective view of the pole-locking key; Fig. 6, aperspective View of the pole-end tip; Fig. '7, a sectional view throughthe pole-end socket with the pole end therein. 7

This invention relates to an improvement in pole-sockets for coaches,carriages, &c., the object of the invention being a construction bywhich the pole is securely held in its socket and rattling prevented;and the invention consists in the construction as hereinafter described,and particularly pointed out in the claims.

In the usual construction of pole-sockets the pole is inserted through asocket and by constant jar or movement soon becomes worn and loose. Toprevent this, I place upon the pole A, which is rectangular incross-section, a sleeve B, corresponding in shape to the pole, so as tofit closely thereon, and tapered to conform to the shape of the pole.This sleeve may be secured by screws 0 or otherwise. This sleeve entersthe usual socket D, which is formed with arms E for attachmentto theunder side of the trace-bar F in the usual manner. The inner end of thepole, which is reduced in diameter, is provided with a metal cap G,which enters a socket H,mounted at a convenient point on therunning-gear. The socket D, which is otherwise of usual construction, isformed with a rearwa'rdly-extending upwardly-bowed centrally-arrangedarm I, in which there is an inclined threaded opening to receive a keyJ, which includes a thumb-piece or head K, a threaded neck L forengagement with the threads in the arm I, and a flattened "point M, thekey J; being bowed, so that the point moves in an eccentric path. In theupper face of the carriagepole A, I arrange a metal block N, upon whichthe point M of the key bears and so that as the key is turned thepoint-M will be forced upon the plate with binding action-to hold thepole in the socket. By forming the sleeve B to closely fit the socket itfollows that the pole cannot become worn, and consequently there will beno rattling.

Should the pole shrink, and so as to be loose in the sleeve, wedges maybe readily inserted between the pole and the sleeve to compensate forsuch shrinkage; but this is a remote possibility, as the wood from whichpoles are formed is usually well seasoned, and the sleeve closelyfittingthe pole and being secured thereto will prevent wear or chafingof thepole.

I am aware that poles have been provided with metal plates on theirupper faces adapted to receive a binding-screw, and therefore do notwish to be understood as claiming broadly such as my invention.

Having fully described my invention, what I claim as new, and desire tosecure byLetters Patent, is- I v 1. The combination with thepole-socket, of a pole havingametal sleeve secured to and surroundingsaid pole and closely fitting the said socket, substantially asdescribed.

2. The combination with the pole-socket, of a pole, a metal sleevesecured to and surrounding said pole and closely fitting said socket, ametal tip surroundingthe inner end of the pole, and a cup-like socketwhich said tip enters and closely fits, substantially as described.

3. The combination with a pole -socket,having rearwardly-extending,upwardly-bowed arm, of a key mounted in said arm, a pole having a metalsleeve secured thereto and adapted to enter said socket, andametal blockin the upper face of said pole upon which said key may bear,substantially as described.

4. The combination with a pole-socket, of

a rearwardly-extending, upwardly-bowed] In testimony whereof I havesigned this arm, a bowed key mounted in said arm, apole specification inthe presence of two subscribhavinga metal sleeve secured thereto and ingwitnesses. adapted to enter said socket, and a metal BERNARD D. DRUEN.
